Google Leases Office Campus at Former Mall from Rockwood, Four Corners

The asset is being repurposed by Rockwood Capital L.L.C. and Four Corners Properties L.L.C. into Class A office space. The space operated as a mall from 1966 to 1986, when Hewlett-Packard bought it and used it as an office campus; it later closed the site. The property had been set to become a 260-unit housing complex. When plans fell through, Rockwood and Four Corners bought the site for $90 million in late 2012. At that time, it was the largest sale of office space in Silicon Valley, according to Kidder Mathews.
